The Rise and Fall of Bitcoin Mining
Early mornings spent commuting, clocking in at work, returning to a rented apartment, cooking meals, and saving diligently for a home—this is the daily routine of Wang Jinghong (pseudonym), a white-collar worker in Dongguan. Two years ago, however, Wang was among the city’s few Bitcoin miners, living a secluded yet lucrative life in a high-end apartment, earning enough to retire within a year. But as Bitcoin’s value plummeted, his frenetic mining days ended, forcing him back into the conventional workforce.
Once hailed as "digital gold," Bitcoin’s value has nosedived—falling 75% in 2024 and another 30% in January 2025—now languishing at 1,400 RMB per coin. This drastic decline shattered investor confidence, prompting many to exit the market.
Key Developments in Bitcoin’s Journey
- 2008: Bitcoin was conceptualized by Satoshi Nakamoto as a decentralized digital currency.
- 2013: Peaked at 8,000 RMB per coin, surpassing gold prices.
- 2024–2025: Prices collapsed by over 75%, erasing gains for many investors.
The Mining Boom and Bust
How Bitcoin Mining Works
Bitcoin mining involves solving complex algorithms using high-powered computers ("mining rigs") to validate transactions and earn new coins. With a capped supply of 21 million, mining grows increasingly difficult over time.
Case Study: Wang Jinghong’s Story
- 2012–2013: Started mining with minimal investment, earning enough to cover lifelong expenses.
- 2014: Mining efficiency dropped—1 coin/day vs. 3 coins/day previously. Soaring electricity costs and declining coin value wiped out his savings.
- 2025: Sold his rigs, returned to a modest lifestyle, and now saves for a home.
Lessons Learned
- Volatility Risk: Bitcoin’s unpredictable swings make it a high-risk investment.
- Sustainability: Mining’s energy-intensive nature and diminishing returns pose long-term challenges.
The Shift Away from Bitcoin
From Crypto to Stocks
Former miner Liao Jun (pseudonym) switched to stock trading after losing 50,000 RMB in Bitcoin. "Stocks offer analytical tools like K-charts—Bitcoin’s volatility is uncontrollable," he remarked.
Regulatory Impact
China’s 2013 ban on financial institutions handling Bitcoin halted its use in transactions, including a Dongguan 4S store that briefly accepted it for car purchases.
